We study how to enhance the transverse magneto-optical Kerr effect (TMOKE) of ultra-thin magnetic dielectric films through the excitation of strong magnetic resonances on metasurface with a metal nanowire array stacked above a metal substrate with an ultra-thin magnetic dielectric film spacer. The plasmonic hybridizations between the Au nanowires and substrate result in magnetic resonances. The periodic arrangement of the Au nanowires can excite propagating surface plasmon polaritons (SPPs) on the metal surface. When the SPPs and the magnetic resonances hybridize, they can strongly couple to form two strong magnetic resonances, which are explained by a coupled oscillator model. Importantly, benefitting from the strong magnetic resonances, we can achieve a large TMOKE signal up to 26% in the ultra-thin magnetic dielectric film with a thickness of only 30 nm, which may find potential applications in nanophotonics, magnonics, and spintronics.

Magneto Optical Kerr Effect

Optical and magneto-optical spectroscopy methods are used to study the properties of one-dimensional spatially-periodic structures formed by a dielectric grating covered with gold and permalloy films. We demonstrate that such structures reveal surface plasmon-polariton excitation with the resonant frequency that can be controlled by the geometry of the experiment. Modulation of the magneto-optical Kerr effect is attained in the spectral vicinity of the plasmon resonance, which is absent for the case of non-structured gold-Py bilayer.
